Organic electroluminescent luminous display and manufacturing method thereof

Abstract

The invention relates to an organic electroluminescent luminous display and a manufacturing method thereof. The display comprises ITO substrate glass, an organic material layer, a metal electrode and a seal cover, wherein a heat-conductive functional layer provided with lattice distributed holes is arranged on the ITO substrate glass; the organic material layer is arranged inside the lattice distributed holes of the heat-conductive functional layer; the metal electrode is arranged on the organic material layer and the heat-conductive functional layer; and the seal cover is arranged on the upmost position. The method comprises the following steps: firstly, preparing the heat-conductive functional layer provided with the lattice distributed holes on the ITO substrate glass; secondly, sequentially performing vapor deposition on the organic material layer and the strip metal electrode; and finally form the organic electroluminescent lighting display through packaging technology. The invention utilizes the heat-conductive functional layer to realize good and quick heat dissipation, and enables the display to have good heat dissipation function. The method reduces the influence probability of impurity particles on the display, and particularly has the performances of high efficiency, energy saving and environmental protection.

Description

Technical field: [0001] The invention relates to an organic electroluminescent lighting display and a manufacturing method thereof, in particular to a manufacturing method of an organic electroluminescent lighting display having a dot-matrix heat conduction functional layer structure. Background technique: [0002] Organic Light Emitting Device (OLED) is widely used in flat panel displays, backlight modules and lighting due to its characteristics of ultra-thin, high brightness, fast response, low power consumption, high efficiency and simple production. The principle of luminescence is to deposit a very thin organic material between two electrodes, and apply direct current to the organic luminescent material to make it luminous. [0003] The practical features of organic electroluminescent lighting displays are high brightness, generally 100~500cd / m 2 Between, the highest brightness can reach 2,000~3,000cd / m 2 ; The second is long-term stable lighting, generally maintainin...

AI Technical Summary

Problems solved by technology

With this method, on the one hand, the heat dissipation problem of the display for lighting cannot be solved; on the other hand, the short-circuit defect caused by impurity particles in the production process cannot be solved.

The above two problems seriously restrict the product application of organic electroluminescent lighting displays, especially for large-area organic electroluminescent lighting displays, not only is it difficult to achieve high brightness, but also the production yield is low
